Kutshanje, i-UL ikhuphe ulwandlalo lwe-UL 9540B Ulwandlalo loPhando loMlilo oMkhulu woVavanyo lweeNkqubo zokuGcina ibhetri yeNdawo yokuHlala. Silindele imibuzo emininzi kwaye ke sinika iimpendulo kwangaphambili.

Q: Yintoni imvelaphi yophuhliso lwe-UL 9540B?

A: Abanye ooGunyaziwe abanoLawulo (AHJs) e-United States babonise ukuba uluhlu lovavanyo lwe-UL 9540A lulodwa lwalunganelanga ukuhlangabezana neemfuno zeKhowudi yoMlilo yaseCalifornia ka-2022, efuna uvavanyo olongezelelweyo lomlilo omkhulu. Ngoko ke, i-UL 9540B yaphuhliswa ngokusekelwe kwigalelo elivela kumasebe omlilo, ebandakanya i-UL 9540A yokuvavanya amava, ejoliswe ekujonganeni neenkxalabo ezivela kwii-AHJs ezahlukeneyo kunye namasebe omlilo.

Q: Yintoni umahluko phakathi UL 9540A kunye UL 9540B?

A:

1. Umda: I-UL 9540B ijolise ngokukodwa kwiinkqubo zokugcina amandla kwindawo yokuhlala ye-20 kWh okanye ngaphantsi, ngaphandle kweenkqubo zokugcina amandla zorhwebo okanye kwimizi-mveliso.
2. Isiqulatho soVavanyo: UL 9540A idinga ukuvavanywa kwiseli, imodyuli, kunye namanqanaba eyunithi, ngelixa i-UL 9540B ifuna kuphela uvavanyo lwezinga leseli kunye novavanyo lokusasazeka komlilo.
3. Ingxelo: I-UL 9540A ivelisa iingxelo zovavanyo ezintathu ezisetyenziselwa ukuvavanya amandla enkqubo yokulawula ukusasazwa kwe-thermal ebalekayo ngenxa yeempazamo zebhetri. I-UL 9540B ivelisa ingxelo yovavanyo enye ejolise ekuphononongeni ukusasazeka komlilo kunye nefuthe layo lobushushu kwindawo engqongileyo.

Umbuzo: Ukuba imveliso igqibile uvavanyo lwe-UL 9540A, ngaba nayiphi na idatha ingasetyenziselwa i-UL 9540B?

A: Ingxelo yovavanyo lweseli ye-UL 9540A ingasetyenziselwa uvavanyo lweseli lwe-UL 9540B. Nangona kunjalo, ngenxa ye-UL 9540B ibe yindlela yokuvavanya eyahlukileyo, uvavanyo lokusasazeka komlilo phantsi kwe-UL 9540B kusafuneka lugqitywe.

Umbuzo: Ngaba iinkqubo zendawo yokugcina amandla zifuna ukuvavanywa phantsi kwe-UL 9540A kunye ne-UL 9540B zombini?

A: Akunjalo. Ukufumana isiqinisekiso se-UL 9540, ngokwemigangatho yofakelo (NFPA 855, IRC), iinkqubo zokugcina amandla kwindawo yokuhlala kufuneka zihlangabezane nemigangatho yokusebenza kweyunithi ye-UL 9540A xa isithuba phakathi kweenkqubo zokugcina amandla ebhetri nganye ingaphantsi kwe-0.9 yeemitha. Ezinye ii-AHJs zinokufuna ukuba abavelisi babonelele ngedatha yovavanyo yovavanyo olukhulu lomlilo olusekwe kwiimfuno zolawulo lwasekhaya, njengeKhowudi yoMlilo yaseCalifornia. Nangona kunjalo, iindlela ezithile zokuvavanya umlilo omkhulu azikapapashwa. I-UL 9540B ijolise ekuboneleleni ngendlela yokuvavanya ehambelanayo yovavanyo lomlilo omkhulu ukuhlangabezana nezi mfuno ze-AHJs.

Q:Indinceda njani i-UL 9540B ukuba ndifumane iimveliso zam zamkelwe e-US okanye kwezinye iimarike?

A: Uvavanyo lwe-UL 9540 kunye novavanyo lwe-UL 9540A luyafuneka kwi-UL 9540 kunye ne-NFPA 855 ukufumana iimveliso zamkelwe e-US nakwezinye iimarike. Nangona kunjalo, imimandla ethile yaseMntla Melika ayicingi ukuba i-UL 9540A imele uvavanyo lomlilo omkhulu njengoko kufunwa yikhowudi yomlilo yendawo-uhlelo lwe-2022 lweKhowudi yoMlilo yaseCalifornia, umzekelo. Kwezo meko, iKhowudi yeKhowudi ifuna uvavanyo olongezelelweyo lomlilo omkhulu kwiinkqubo zokugcina amandla okuhlala, kwaye kulapho i-UL 9540B ingena khona. I-UL 9540B yaphuhliswa ukujongana neenkxalabo zamagunya ekhowudi enxulumene nemingcipheko yokusasaza umlilo kwi-ESS yokuhlala. amava ngenxa isiganeko thermal run ekusasazweni.

Q:Ngaba i-UL 9540B yenzelwe ukuba ibe nguMgangatho?

A: Ewe, kukho izicwangciso zokwenza i-UL 9540B ibe ngumgangatho ofanayo no-UL 9540A. Okwangoku i-UL 9540B ikhutshwe njengolwandlalo lokujongana neemfuno zangoku ze-AHJ.
